Answer 2

Step-by-step explanation:

GIVEN :

A box contains 4 balls,1 red, 1 green, 1 yellow and 1 blue.

TO FIND: the probability of getting a red ball

SOLUTION:

No.of red balls =n(R)=1

No. of green balls=n(G)=1

No. of yellow balls=n(Y)=1

No. of blue balls =n(B)=1

Total number of balls in the bag =4

Let getting the red ball is an event P(R)

then,

No. of favourable outcomes =1

Total no.of possible outcomes=4

Probability that getting a red ball =

No. of favourable outcomes/Total no. of possible outcomes

P(R)=1/4 or 0.25 or 25%
